Novel quinuclidine derivatives and medicinal compositions containing the same

ABSTRACT

Carbamates of formula (I) or pharmaceutically acceptable salts thereof, including quaternary ammonium salts of formula (II) are disclosed; as well as processes for their preparation, pharmaceutical compositions comprising them and their use in therapy as antagonists of M3 muscarinic receptors.

This invention relates to new therapeutically useful quinuclidine carbamate derivatives, to some processes for their preparation and to pharmaceutical compositions containing them.

The structures according to the invention are antimuscarinic agents with a potent and long lasting effect. In particular, these compounds show high affinity and selectivity for muscarinic M3 receptors over M2 receptors. The M3 subtype of muscarinic receptor is present in glands and smooth muscle and mediates the excitatory effects of the parasympathetic system on glandular secretion and on the contraction of visceral smooth muscle (Chapter 6, Cholinergic Transmission, in H. P. Rang et al., Pharmacology, Churchill Livingstone, New York, 1995).

M3 antagonists are therefore known to be useful for treating diseases characterised by an increased parasympathetic tone, by excessive glandular secretion or by smooth muscle contraction (R. M. Eglen and S. S. Hegde, (1997), Drug News Perspect., 10(8):462-469).

Examples of this kind of diseases are respiratory disorders such as chronic obstructive pulmonary disease (COPD), bronchitis, bronchial hyperreactivity, asthma, cough and rhinitis; urological disorders such as urinary incontinence, pollakiuria, neurogenic or unstable bladder, cystospasm and chronic cystitis; gastrointestinal disorders such as irritable bowel syndrome, spastic colitis, diverticulitis and peptic ulceration; and cardiovascular disorders such as vagally induced sinus bradycardia (Chapter 7, Muscarinic Receptor Agonists and Antagonists, in Goodman and Gilman's The Pharmacological Basis of Therapeutics, 10th edition, McGraw Hill, New York, 2001.).

The compounds of the invention can be used alone or in association with other drugs commonly regarded as effective in the treatment of these diseases. For example, they can be administered in combination with β₂-agonists, steroids, antiallergic drugs, phosphodiesterase IV inhibitors and/or leukotriene D4 (LTD4) antagonists for simultaneous, separate or sequential use in the treatment of a respiratory disease.

The present invention provides new quinuclidine carbamate derivatives with potent antagonist activity at muscarinic M3 receptors, which fall under the chemical structure described in formula (I) or are pharmaceutically acceptable salts thereof, including quaternary salts of formula (II).

The present invention also provides processes for preparing compounds of formulas (I) and (II).

Compounds of general formula (I) may be prepared by method (a) illustrated in the following scheme and detailed in the experimental section.

In formulas (I), (III) and (IV), R1, R2 and p are as defined above.

Compounds of general formula (III) may be prepared from the corresponding secondary amines following the standard method (b) described in literature.

Amines of general formula (V) that are not commercially available may be prepared by synthesis according to standard methods, such as alkylation of anilines or reductive alkylation. For example, amines wherein R1 is a substituted thiophen-2-ylmethyl or a substituted furan-2-ylmethyl and R2 is as defined above, may be obtained by reductive alkylation. The corresponding aldehyde is treated with the corresponding primary amine to form the imine, which is reduced with sodium borohydride in MeOH to obtain the secondary amine.

The carbamates of formula (I) may be converted to pharmaceutically acceptable salts by methods known in the art. Typically, a carbamate of formula (I) is treated with an inorganic or organic acid such as fumaric, tartaric, formic, succinic or hydrochloric acid.

The quaternary ammonium derivatives of general formula (II), may be prepared by reaction of an alkylating agent of general formula (VI) with compounds of general formula (I), as described in the following scheme. In formulas (I), (II) and (VI), R1, R2, A, B, X, n, m and p are as defined above.

In formula (VI), W represents any suitable leaving group, such as a group X as defined above. Preferably, W represents a group X.

This alkylation reaction may be carried out by two different experimental procedures, (c) and (d) which are described in the experimental section below. In particular method (d) provides a new experimental process, using solid phase extraction methodologies that allow the parallel preparation of several compounds. If W represents a group other than X, the quaternary ammonium salt of formula (II) is produced from the product of method (c) or (d) by carrying out an exchange reaction according to standard methods to replace the anion W with the desired anion X⁻.

Methods (c) and (d) are described in the experimental section. Compounds of general formula (VI) which are not commercially available have been prepared by synthesis according to standard methods. For example, compounds wherein n=0 and A=—O—, —S— or —NR4, wherein R4 is as defined above, were obtained by reaction of the corresponding alcohol, thiol or amine derivative or its sodium or potassium salt with an alkylating agent of general formula Y—(CH₂)m-W, wherein W may be a halogen and Y may be a halogen or a sulphonate ester. In other examples, compounds of general formula (VI), where n>=1 were synthesised from the corresponding alcohol derivative of general formula (VII) by known methods.

B—(CH₂)_(n)-A-(CH₂)_(m)—OH  (VII)

Compounds of formula (IV) could be:

4-hydroxy-1-azabicyclo[2.2.1]heptane, described in WO93/15080 4-hydroxy-1-azabicyclo[2.2.2]octane, described in Grob, C. A. et. al. Helv. Chim. Acta (1958), 41, 1184-1190 (3R)-3-hydroxy-1-azabicyclo[2.2.2]octane or (3S)-3-hydroxy-1-azabicyclo[2.2.2]octane, described in Ringdahl, R. Acta Pharm Suec. (1979), 16, 281-283 and commercially available from CU Chemie Uetikon GmbH.

The structures of the prepared compounds were confirmed by ¹H-NMR and MS. The NMR were recorded using a Varian 300 MHz instrument and chemical shifts are expressed as parts per million (δ) from the internal reference tetramethyl silane.

Pharmacological Action

The following examples demonstrate the excellent pharmacological activities of the compounds of the present invention. The results on human muscarinic receptor binding and in the test on bronchospasm in guinea pig, were obtained as described below.

Human Muscarinic Receptor Studies.

The binding of [³H]-NMS to human muscarinic receptors was performed according to Waelbroeck et al (1990), Mol. Pharmacol., 38: 267-273. Assays were carried out at 25° C. Membrane preparations from stably transfected Chinese hamster ovary-K1 cells (CHO) expressing the genes for the human muscarinic M3 receptors were used.

For determination of IC₅₀, membrane preparations were suspended in DPBS to a final concentration of 89 μg/ml for the M3 subtype. The membrane suspension was incubated with the tritiated compound for 60 min. After incubation the membrane fraction was separated by filtration and the bound radioactivity determined. Non specific binding was determined by addition of 10⁻⁴ M atropine. At least six concentrations were assayed in duplicate to generate individual displacement curves. Our results show that the compounds of the present invention have high affinities for muscarinic M3 receptors. Preferred compounds of the invention have an IC₅₀ (nM) value for M3 receptors of less than 35 nM, most preferably less than 10 nM.

The preferred compounds of the invention also show high selectivity for M3 receptors with respect to M2 receptors. Thus, the ratio IC₅₀ M2/IC₅₀ M3 is higher than 5, preferably higher than 10, most preferable higher than 15.

Test on Bronchospasm in Guinea Pig

The studies were performed according to H. Konzett and F. Rössler (1940), Arch. Exp. Path. Pharmacol. 195, 71-74. Aqueous solutions of the agents to be tested were nebulized and inhaled by anaesthetized ventilated male guinea pigs (Dunkin-Hartley). Bronchial response to intravenous acetylcholine challenge was determined before and after drug administration and changes in pulmonary resistance at several time-points were expressed as percent of inhibition of bronchospasm.

The compounds of the present invention showed bronchodilator activity with high potency and a long duration of action.

From the above described results one of ordinary skill in the art can readily understand that the compounds of the present invention have excellent antimuscarinic activity (M3) and thus are useful for the treatment of diseases in which the muscarinic M3 receptor is implicated, including respiratory diseases such as chronic obstructive pulmonary disease, bronchitis, asthma, bronchial hyper reactivity and rhinitis; urinary diseases such as urinary incontinence, pollakiuria, neurogenic bladder, nocturnal enuresis, unstable bladder, cystospasm and chronic cystitis; gastrointestinal diseases such as irritable bowel syndrome, spastic colitis, diverticulitis and peptic ulceration; and cardiovascular disorders such as vagally induced sinus bradicardia. For example, the compounds of the present invention are useful for the treatment of respiratory diseases such as chronic obstructive pulmonary disease, chronic bronchitis, asthma, and rhinitis; urinary diseases such as urinary incontinence and pollakinuria in neuripenia pollakinuria, neurogenic bladder, nocturnal enuresis, unstable bladder, cytospasm and chronic cystitis; and gastrointestinal diseases such as irritable bowel syndrome, spastic colitis and diverticulitis.

The present invention further provides a compound of formula (I) or (II) or a pharmaceutically acceptable composition comprising a compound of formula (I) or (II) for use in a method of treatment of the human or animal body by therapy, in particular for the treatment of respiratory, urinary or gastrointestinal disease.

The present invention further provides the use of a compound of formula (I) or (II) or a pharmaceutically acceptable composition comprising a compound of formula (I) or (II) for the manufacture of a medicament for the treatment of respiratory, urinary or gastrointestinal disease.

Further, the compounds of formula (I) or (II) and pharmaceutical compositions comprising a compound of formula (I) or (II) can be used in a method of treating respiratory, urinary or gastrointestinal disease, which method comprises administering to a human or animal patient in need of such treatment an effective amount of a compound of formula (I) or (II) or a pharmaceutical composition comprising a compound of formula (I) or (II).

Further, the compounds of formula (I) or (II) and pharmaceutical-compositions comprising a compound of formula (I) or (II) can be used in combination with other drugs effective in the treatment of these diseases. For example with β₂ agonists, steroids, antiallergic drugs, phosphodiesterase IV inhibitors and/or leukotriene D4 (LTD4) inhibitors, for simultaneous, separate or sequential use in the treatment of a respiratory disease.

The present invention therefore provides a combination product comprising

-   -   (i) a compound according to the invention; and     -   (ii) another compound effective in the treatment of a         respiratory, urological or gastrointestinal disease or disorder

for simultaneous, separate or sequential use.

The compound (II) which is effective in the treatment of a respiratory, urological or gastrointestinal disease or disorder may be a β₂ agonist, steroid, antiallergic drug, phosphodiesterase IV inhibitor and/or leukotriene D4 (LTD4) antagonist. Preferably, the product is for simultaneous, separate or sequential use in the treatment of a respiratory disease.
